When we see records being broken and unprecedented events such as this, the onus is on those who deny any connection to climate change to prove their case. Global warming has fundamentally altered the background conditions that give rise to all weather. In the strictest sense, all weather is now connected to climate change. Kevin Trenberth

James Taylor misinterprets study by 180 degrees

In a Forbes op-ed, James Taylor takes a study that prominently reveals the anti-science influence of oil and gas companies, and spins it to suggest that serious, substantive disagreement exists among relevant scientists on climate change. This could not be further from the truth, as evidenced by the very study he cites, as well as numerous other studies that have surveyed climate scientists.

In a Forbes op-ed, James Taylor takes a study that prominently reveals the anti-science influence of oil and gas companies, and spins it to suggest that serious, substantive disagreement exists among relevant scientists on climate change. This could not be further from the truth, as evidenced by the very study he cites, as well as numerous other studies that have surveyed climate scientists.

The claim:

Taylor references a new study that surveyed Canadian engineers and geoscientists in the province of Alberta. He attaches the headline, “Peer-Reviewed Survey Finds Majority of Scientists Skeptical of Global Warming Crisis.” The study divides respondents into 5 groups, and Taylor highlights the fact that only 36% of scientists fell into the category most supportive of climate action. He concludes, “…it is becoming clear that not only do many scientists dispute the asserted global warming crisis, but these skeptical scientists may indeed form a scientific consensus.”

The context:

- The study Taylor references polled members of the Association of Professional Engineers and Geoscientists of Alberta (APEGA). Membership in APEGA is a prerequisite to a job with an oil, gas, or mining company, and these jobs dominate its online job board. Alberta, home to the tar sands boom, is Canada’s most oil-rich province, and the petroleum industry is Alberta’s largest employer of engineers and geoscientists.

- The study authors used the APEGA survey as a way to see how extractive industry positions influence scientific views and justifications. They found that people employed by oil and gas companies were much more likely to oppose mainstream climate science. Additionally, the more highly placed in the company, the more vehement the opposition.

- 84% of the respondents to the survey were engineers. This designation includes many subspecialties that have nothing to do with climate, for example electrical engineers and pipeline corrosion specialists.

- Taylor’s focus on the most concerned category of scientists and engineers is misleading. Another 5% of respondents supported moderate action, and an additional 17% believed that humans were influencing the climate, although they were not sure if action was needed. This means that even among a group made up primarily of oil and gas industry engineers, 58% believed that humans are influencing the climate.

Additional studies:

- A recent literature review found that out of 13,950 peer-reviewed climate science studies since 1991, only 24 reject human-caused global warming.

- A peer-reviewed survey of 1,372 actively publishing climate researchers found that 97% of them uphold the existence of human-caused global warming.

- Another peer-reviewed survey of 10,257 earth scientists from a variety of disciplines also found 97% agreement among actively publishing climate scientists, and almost 90% agreement among all actively publishing earth scientists that humans are causing global warming.

Conclusion:

The APEGA survey is noteworthy for its exposure of the disparity between the views of engineers and geoscientists employed by petroleum companies, vs. the rest of the community of actively publishing climate and earth scientists. Denialism increased still further among the top-level oil and gas engineers. Although the cause behind this trend is unclear, it shows at the very least a correlation between ties to oil and gas and climate denial views. In no way does it undermine the strong agreement among publishing scientists that human-caused global warming is real and a problem.
